PnL Labs — MCP server & x402 API
Trust & risk verdicts for AI trading agents on Solana. Proof of real PnL,
not peak scores. Pay-per-call via x402 (USDC on Solana) —
no signup, no API key, no account.

Connect in 10 seconds (hosted MCP — no install)
The server is hosted. Add it to any MCP-capable assistant with one URL:
https://api.pnllabs.com/mcp
- Claude (all plans): Settings → Connectors → Add custom connector
- Grok: grok.com/connectors → Custom
- ChatGPT / Gemini: custom MCP connector → same URL
- Also listed in the official MCP Registry (
io.github.PnLlabs/pnllabs) and on Smithery.
Free tier per IP/day — when it runs out, the tools reply with structured
x402 payment instructions (pay-per-call, USDC on Solana).
Why
Every "smart money" score you've seen ranks wallets by peak or paper gains.
Peaks lie. A wallet can 100x on paper, dump into no liquidity, and walk away red —
while its score still says genius. We audited 30 tracked "smart money" wallets and
half of them are genuinely losing money on-chain.
PnL Labs recomputes what actually hit the wallet — realized SOL, in vs out — and
returns a conservative, machine-readable verdict. When the numbers can't be
reconstructed reliably, it says UNVERIFIABLE instead of guessing.
The four checks
| Endpoint | Question | Verdicts |
|---|
GET /check/wallet/{address} | Is this wallet worth copying? (real realized PnL) | TRUSTED · NEUTRAL · UNTRUSTED · INSUFFICIENT · UNVERIFIABLE |
GET /check/funder/{address} | Where did this wallet's money come from? (funding origin / cluster links) | CEX_FUNDED · WALLET_FUNDED · UNKNOWN_ORIGIN · UNVERIFIABLE_ORIGIN |
GET /check/token/{mint} | Is this token structurally safe? | LOW_RISK · ELEVATED · HIGH_RISK · CRITICAL · UNKNOWN |
GET /check/trade/{mint}?size_sol=1 | What will this trade really cost? (real slippage) | ACCEPTABLE_COST · ELEVATED_COST · HIGH_COST · UNTRADEABLE · NO_POOL |
Every response carries a stable verdict enum, machine-readable reasons (code +
message), confidence, flags, and schema_version. Built to be parsed by agents,
not read by humans. Interactive docs: https://api.pnllabs.com/docs.
Quick example
curl https://api.pnllabs.com/check/wallet/57hECCDVNmP7jCY6XX6FxP31DQuKiwQhv2g3nxGPLPmV
{
"schema_version": 1,
"verdict": "UNTRUSTED",
"confidence": "high",
"trust": 15,
"reasons": [
{ "code": "NEGATIVE_REALIZED_PNL", "message": "Genuinely NEGATIVE: -47.1 SOL net realized" },
{ "code": "LOW_WIN_RATE", "message": "Only 27% of coins were profitable" }
]
}
MCP server
This repo ships an MCP server exposing the four
checks as tools (check_wallet_trust, check_wallet_forensics, check_token_safety,
check_trade_cost). It calls the hosted API — no RPC keys or local setup needed.
Add to an MCP client (e.g. Claude Desktop / Claude Code):
{
"mcpServers": {
"pnllabs": {
"command": "python3",
"args": ["/path/to/pnllabs_mcp.py"]
}
}
}
Runs on the Python standard library — no dependencies for the free/beta tier.
Payment (x402)
Calls are priced per request and paid in USDC on Solana via the x402 protocol
(HTTP 402). Your agent pays a few cents, gets an on-chain receipt — no accounts,
no keys stored anywhere. Prices: wallet 0.10, funder 0.05, token/trade 0.02 USDC.
Any x402-capable client (or the official x402 SDKs) can pay automatically.
Honest scope
- Wallet trust & forensics are the core edge — realized-PnL truth and funding
origin, which peak-based scores and EVM-only tools don't provide on Solana.
- Token safety flags structural red flags with zero noise. Behavioral rugs
(an operator selling into his own hype) are invisible to all structural
checkers — for those, check the wallets involved.
- We sell risk/trust verdicts, not alpha. Never "when to buy."
